Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions. the statement "<span>a pair of straight angles can also be adjacent angles" is true
</span>There are some special relationships between "pairs<span>" of </span>angles<span>. </span>Adjacent Angles<span> are two </span>angles<span> that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) A Linear </span>Pair<span> is two </span>adjacent angles<span>whose non-common sides form opposite rays.</span>
